To @Z310/tom z' may concern:

Re it known that we, JOHN L; FAY and Fnnonrcn BIELHEN, citizens of theUnited States, residing at St. Louis, Missouri, have invented a certainnew and useful improvement in Pole-Erectors, of which the following is afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

Our invention relates to an apparatus for erecting poles which carry theoverhead wires and cables utilized in telegraph, telephone andelectric-light service, the principal object of our invention being toprovide a comparatively simple apparatus which will be eective ineliminating much of the time, labor and consequent expense now involvedin the erection ot poles, said apparatus being mounted on a truck inorder that it may be readily moved to and Jfrom the points of use andthe operating parts of the apparatus being adjustable upon the bed ofthe truck in order to facilitate the work involved in the erection ofpoles. j

Further objects of our invention are to provide an improved poleerecting device which includes a gin pole, the same being equipped witha suitable block and tackle which is utilized in lifting the poles whichare to be erected to mount the gin pole and its operating mechanism upona base and to mount the latter for transverse sliding movement upon therear portion of the bed or platform of the truck utilized fortransporting the erecting device, and Vfurther toV provide meanspreferably cooperating racks, pinions and worm gearing for readilyshifting the gin ole from an approximate horizontalposition on the bedof the truck to a vertical position or vice versa and for raising orlowering the gin pole for a limited distance after it has been swunginto a vertical position. By utilizing coperating racks,` pinions andworm gearing as the means for raising and lowering the gin pole,

weare able to dispense with cables, winding drums, clutches and likeparts usually em-.

ployed for raising and lowering the gin ole. j

With the foregoing and other objects in view, our invention consists incertain novel features of construction and arrangement of parts,hereinafter more fully described, claimed and illustrated in theaccompanying drawings, in which- Figure 1 is an elevational view or' atruck, the same being equipped with a pole erectfig device et ourimproved construction.

Fig. 2 is an enlarged side elevational view or" the rear portion of thebed 01"' the truck and showing the operating parts of the erectingdevice.

Fig. 3 is a vertical section taken approximately on the line 3--3 of Fig. 2.

Fig. a is an elevational view partly in section and showing the gin polein vertical position. j

Fig. 5 is an elevational view looking in the direction indicated by thearrow 5 in Fig. t, and showing the lower end of the gin pole in section.

Fig. 6 is an enlarged horizontal section taken approximately on the line6--6 of Fig. 4. Y i

Referring by numerals to the accompanying drawings, 10 designates thebed of a truck, either horse-drawn or motor-driven and fixed to the rearond of said bed and extending the entire width thereof is an angle rail11.

VFixed on top of the bed a short distance in front of this angle rail`and occupying a position parallel therewith is a Z-bar 12, and xed tothe bed immediately adjacent to said angle and Z-bar are straps 18.

Arranged for sliding movement upon these straps and between thel members11 and 12 is a plate 111: which serves as a base for the operatingmechanism of our improved device.

Fixed to plate 1d are pairs of upwardly j projecting brackets 15, theupper ends of which are provided with journal boxes 16 which receive theends of a shaft 17 and mounted on this shaft between the journal box isa quadrant plate 1S, the same being provided with teeth 19.

Formed integral with or xed to this quadrant plate is a pair or rackbars 20, with the ends of which are formed integral blocks 20a, the samehaving sliding connec` tion, Vpreferably with a rib 21, which latter isformed integral with a plate 22, the latter being rigidly lixed in anysuitable manner to the lower portion of a gin pole 23.

`Asillustrated, the blocks 20L have dovetailed joint connections withthe rib 21, al-

though-1 any other fol-ln of sliding eonneetion may be utilized asdesired.

Fixed to the bottom ot the gin pole23 is a plate 24 with which is formedintegral one 5 or more prongs 25, the saine being adapted to enter theground on which the gin pole is positioned, thereby assisting inmaintaining said pole in a rigid and substantial upright position. Theupper end oiitlfie' gin pole is 10 provided with a sheave 26 aroundwhich passestlie cable 27 of a bloeit and' tackle (not sli-own). Fixedto thenpper end of thegiir pole are rings or eesQS, "Wl'iiclr'areadapted to" receive guy ropesor the likeutilfi-Zcd for l5' stajf'ing"the gin pole When the's'aine is in op;

Positioned between' rib :'21 and the `rack barsQ' is a fnielnloercomprising a centrally arranged Worin Wheel 29 and a `pfair" of pin! 2o'ions 20, which latter are constantly 'inL inesh Wlfjlitli'teetl'lpftllclfbirs 20.

the ground.

sult that the gin pole is swung downward into a substantially horizontalposition as illustrated in Fig. l.

1t will be understood that the weightl of the gin pole while in avertical position and before its lower end rests upon the ground, ist1ansmitted through worm 33, worm wheel 29 and pinions 30 to rack bars20, from thence through shaft 17 and brackets supporting the same toplate le, which latter rests upon the bed of the truck, and further thatthis arrangement of parts particularly the worm and worm wheelpractically locks the gin pole against downward movement by reason ofits weight, after said gin pole has been swung into a vertical positionand before it has been lowered into contact with It will be noted thatwe employ means, preferably a pinion and toothed. quadrant plate, forshifting the gin pole from a horizontal to a vertical position and viceversa, and that we provide a Vdifferent means which preferably includescoperating racks, pinions and worm gearing for raising or lowering thegin pole after it has been swung into a vertical position. By virtue ofthese mechanisms, all cables, winding drums, clutches and the likeusually employed for the gin pole raising and lowering means areeliminated and the raising and lowering operations can be effectedquickly and with comparatively little effort on the part of theoperators.

A pole erecting apparatus of our improved construction is comparativelysimple, can be easily and quickly shifted into and out of operativeposition, can be readily -moved from one side of the truck to the other,and by its use a material saving of the time, labor and consequentexpense now involved in the setting of wire carrying poles is eifected.

It will be readily understood that minor changes in the size, form andconstruction of the various parts of our improvedpole erecting apparatuscan be made and substituted for those herein shown and described,without departing from the spirit of our invention, the scope of whichis set forth in the appended claims.
